About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-100S
The AirTAC SAIJ80X210-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a substantial 4523N push force at 0.9 MPa and provides a usable travel window of 110 to 210 mm. This wide adjustment range allows you to dial back the nominal 210 mm stroke by up to 100 mm during commissioning.
This unit includes a magnet for CMSE reed and DMSE electronic sensors, utilizing the dual sensor grooves machined into the extruded aluminum barrel. It uses a robust 25 mm carbon steel rod with an M20x1.5 thread, and PT tapered port threading for the G3/8 air supply. The rear adjuster acts purely as a mechanical stop to set the retract end position, so it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-100S Is Used
Product Changeover
Quickly dial the retract stop back by up to 100 mm to accommodate different package lengths on a packaging line without changing the cylinder.
End-Position Tuning
Fine-tune the exact retract distance during machine commissioning to perfect a pressing or forming operation without adding external stops.
Variable Forming
Adjust the travel window from 110 to 210 mm to handle varying material thicknesses or sizes in a single multi-product work cell.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-100S the Right Cylinder?
Choose this 80 mm bore when an application requires high thrust, such as 4523N at 0.9 MPa, but still needs the flexibility to vary the end-stop without swapping cylinders. If your setup only needs 3518N of push force, stepping down to the 63 mm bore saves space, while moving up to the 100 mm bore yields 7068N for heavier loads. The 100 mm adjustment range is ideal for product-size changeovers on a single line.
Because the stroke is 210 mm, which is 300 mm or less, side-load risks are moderate, but an external guide is still recommended for heavy loads. For load-holding without continuous air pressure, this standard adjuster cannot lock the position; you would need an SAIL or BSAI cylinder instead. This SKU is dimensionally interchangeable per ISO 15552 and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-100S FAQ
The rear stopper screw lets you shorten the effective stroke from its nominal 210 mm down to as little as 110 mm, giving a 100 mm adjustment window. The adjuster is a mechanical stop, not a lock, so it cannot hold a load without live air pressure.
At 0.9 MPa, the SAIJ80X210-100-S provides a push force of 4523N and a pull force of 2268N. It operates at speeds between 30 and 800 mm/s.
